[0089] The term “heteroaryl” as used herein represents an unsubstituted or substituted stable five or six membered monocyclic heteroaromatic ring system or an unsubstituted or substituted stable nine or ten membered bicyclic heteroaromatic ring system and unsubstituted or substituted stable twelve to fourteen membered tricyclic ring systems which consists of carbon atoms and from one to four heteroatoms selected from N, O or S, and wherein the nitrogen heteroatom of any of these heteroaryls may optionally be oxidized, or may optionally be quaternized. Preferred heteroaryl are aromatic monocyclic rings containing five members of which at least one member is a N, O or S atom and which optionally contains one, two or three additional N atoms; an aromatic monocyclic ring having six members of which one, two or three members are a N atoms; an aromatic bicyclic ring having nine members of which at least one member is a N, O or S atom and which optionally contains one, two or three additional N atoms; an aromatic bicyclic ring having ten members of which of which one, two, three or four members are N atoms; or, an aromatic tricyclic ring system containing 13 members of which at least one member is a N, O or S atom and which optionally contains one, two or three additional N atoms. In another embodiment of this invention, the previously defined heteroaryls have as the additional heteroatom N, wherein at most four nitrogens atoms are adjacent. Examples include, and are not limited to, furyl, thienyl, pyrrolyl, oxazolyl, thiazolyl, imidazolyl, triazolyl, tetrazolyl, pyrazolyl, isoxazolyl, isothiazolyl, pyridinyl, pyridazinyl, pyrimidinyl, pyrazinyl, indolyl, indazolyl, benzo(b)thienyl, quinolinyl, isoquinolinyl or quinazolinyl.

[0090] Whenever the term “alkyl” or “aryl” or either of their prefix roots appear in a name of a substituent (e.g., aralkyl, alkylamino) it shall be interpreted as including those limitations given above for “alkyl” and “aryl.” Designated numbers of carbon atoms (e.g., C₁-C₆) shall refer independently to the number of carbon atoms in an alkyl or cycloalkyl moiety or to the alkyl portion of a larger substituent in which alkyl appears as its prefix root.

[0091] Under standard nomenclature rules used throughout this disclosure, the terminal portion of the designated side chain is described first followed by the adjacent functionality toward the point of attachment. Thus, for example, a “phenylC₁₋₆alkylamidoC₁₋₆alkyl” substituent refers to a group of the formula:

[0092] A substituent's point of attachment may also be indicated by a dashed line to indicate the point(s) of attachment, followed by the adjacent functionality and ending with the terminal functionality such as, for example, _—(C₁₋₆)alkyl-NH—(C₁₋₆)alkyl-phenyl.

[0093] It is intended that the definition of any substituent or variable at a particular location in a molecule be independent of its definitions elsewhere in that molecule. It is understood that substituents and substitution patterns on the compounds of this invention can be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by techniques known in the art as well as those methods set forth herein.

[0094] An aspect of the invention is a pharmaceutical composition comprising a pharmaceutically acceptable carrier and any of the compounds described above. Illustrative of the invention is a pharmaceutical composition made by mixing any of the compounds described above and a pharmaceutically acceptable carrier. Another illustration of the invention is a process for making a pharmaceutical composition comprising mixing any of the compounds described above and a pharmaceutically acceptable carrier. Further illustrative of the present invention are pharmaceutical compositions comprising one or more compounds of this invention in association with a pharmaceutically acceptable carrier.

[0095] As used herein, the term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combinations of the specified ingredients in the specified amounts.

[0096] The compounds of the present invention are selective kinase or dual-kinase inhibitors useful in a method for treating or ameliorating a kinase or dual-kinase mediated disorder. In particular, the kinase is selected from protein kinase C or glycogen synthase kinase-3. More particularly, the kinase is selected from protein kinase C α, protein kinase C β-II, protein kinase C γ or glycogen synthase kinase-3β.

[0097] Protein Kinase C Isoforms

[0098] Protein kinase C is known to play a key role in intracellular signal transduction (cell-cell signaling), gene expression and in the control of cell differentiation and growth. The PKC family is composed of twelve isoforms that are further classified into 3 subfamilies: the calcium dependent classical PKC isoforms alpha (α), beta-I (β-I), beta-II (β-II) and gamma (γ); the calcium independent PKC isoforms delta (δ), epsilon (ε), eta (η), theta (θ) and mu (μ); and, the a typical PKC isoforms zeta (ζ), lambda (λ) and iota (ι).

[0099] Certain disease states tend to be associated with elevation of particular PKC isoforms. The PKC isoforms exhibit distinct tissue distribution, subcellular localization and activation-dependent cofactors. For example, the α and β isoforms of PKC are selectively induced in vascular cells stimulated with agonists such as vascular endothelial growth factor (VEGF) (P. Xia, et al., J. Clin. Invest., 1996, 98, 2018) and have been implicated in cellular growth, differentiation, and vascular permeability (H. Ishii, et al., J. Mol. Med., 1998, 76, 21). The elevated blood glucose levels found in diabetes leads to an isoform-specific elevation of the β-II isoform in vascular tissues (Inoguchi, et al., Proc. Natl. Acad. Sci. USA, 1992, 89,11059-11065). A diabetes-linked elevation of the β isoform in human platelets has been correlated with their altered response to agonists (Bastyr III, E. J. and Lu, J., Diabetes, 1993, 42, (Suppl. 1) 97A). The human vitamin D receptor has been shown to be selectively phosphorylated by PKCβ. This phosphorylation has been linked to alterations in the functioning of the receptor (Hsieh, et al., Proc. Natl. Acad. Sci. USA, 1991, 88, 9315-9319; Hsieh, et al., J. Biol. Chem., 1993, 268, 15118-15126). In addition, the work has shown that the β-II isoform is responsible for erythroleukemia cell proliferation while the α isoform is involved in megakaryocyte differentiation in these same cells (Murray, et al., J. Biol. Chem., 1993, 268, 15847-15853).

[0100] Cardiovascular Diseases

[0101] PKC activity plays an important role in cardiovascular diseases. Increased PKC activity in the vasculature has been shown to cause increased vasoconstriction and hypertension (Bilder, G. E., et al., J. Pharmacol. Exp. Ther., 1990, 252, 526-530). PKC inhibitors block agonist-induced smooth muscle cell proliferation (Matsumoto, H. and Sasaki, Y., Biochem. Biophys. Res. Commun., 1989, 158, 105-109). PKC β triggers events leading to induction of Egr-1 (Early Growth Factor-1) and tissue factor under hypoxic conditions (as part of the oxygen deprivation-mediated pathway for triggering procoagulant events) (Yan, S-F, et al., J. Biol. Chem., 2000, 275, 16, 11921-11928). PKC β is suggested as a mediator for production of PAI-1 (Plaminogen Activator Inhibitor-1) and is implicated in the development of thrombosis and atherosclerosis (Ren, S, et al., Am. J. Physiol., 2000, 278, (4, Pt. 1), E656-E662). PKC inhibitors are useful in treating cardiovascular ischemia and improving cardiac function following ischemia (Muid, R. E., et al., FEBS Lett., 1990, 293,169-172; Sonoki, H. et al., Kokyu-To Junkan, 1989, 37, 669-674). Elevated PKC levels have been correlated with an increased platelet function response to agonists (Bastyr III, E. J. and Lu, J., Diabetes, 1993, 42, (Suppl. 1) 97A). PKC has been implicated in the biochemical pathway in the platelet-activating factor (PAF) modulation of microvascular permeability (Kobayashi, et al., Amer. Phys. Soc., 1994, H1214-H1220). PKC inhibitors affect agonist-induced aggregation in platelets (Toullec, D., et al., J. Biol. Chem., 1991, 266, 15771-15781). Accordingly, PKC inhibitors may be indicated for use in treating cardiovascular disease, ischemia, thrombotic conditions, atherosclerosis and restenosis.

[0102] Diabetes

[0103] Excessive activity of PKC has been linked to insulin signaling defects and therefore to the insulin resistance seen in Type II diabetes (Karasik, A., et al., J. Biol. Chem., 1990, 265,10226-10231; Chen, K. S., et al., Trans. Assoc. Am. Physicians, 1991, 104, 206-212; Chin, J. E., et al., J. Biol. Chem., 1993, 268, 6338-6347).

[0104] Diabetes-Associated Disorders

[0105] Studies have demonstrated an increase in PKC activity in tissues known to be susceptible to diabetic complications when exposed to hyperglycemic conditions (Lee, T-S., et al., J. Clin. Invest., 1989, 83, 90-94; Lee, T-S., et al., Proc. Natl. Acad. Sci. USA, 1989, 86, 5141-5145; Craven, P. A. and DeRubertis, F. R., J. Clin. Invest., 1989, 87,1667-1675; Wolf, B. A., et al., J. Clin. Invest., 1991, 87, 31-38; Tesfamariam, B., et al., J. Clin. Invest., 1991, 87,1643-1648). For example, activation of the PKC-β-II isoform plays an important role in diabetic vascular complications such as retinopathy (Ishii, H., et al., Science, 1996, 272, 728-731) and PKCβ has been implicated in development of the cardiac hypertrophy associated with heart failure (X. Gu, et al., Circ. Res., 1994, 75, 926; R. H. Strasser, et al., Circulation, 1996, 94,1551). Overexpression of cardiac PKCβII in transgenic mice caused cardiomyopathy involving hypertrophy, fibrosis and decreased left ventricular function (H. Wakasaki, et al., Proc. Natl. Acad. Sci. USA, 1997, 94, 9320).

[0106] Inflammatory Diseases

[0107] PKC inhibitors block inflammatory responses such as the neutrophil oxidative burst, CD3 down-regulation in T-lymphocytes and phorbol-induced paw edema (Twoemy, B., et al., Biochem. Biophys. Res. Commun., 1990, 171, 1087-1092; Mulqueen, M. J., et al. Agents Actions, 1992, 37, 85-89). PKC β, has an essential role in the degranulation of bone marrow-derived mast cells, thus affecting cell capacity to produce IL-6 (Interleukin-6) (Nechushtan, H., et al., Blood, 2000 (March), 95, 5, 1752-1757). PKC plays a role in enhanced ASM (Airway Smooth Muscle) cell growth in rat models of two potential risks for asthma: hyperresponsiveness to contractile agonists and to growth stimuli (Ren, S, et al., Am. J. Physiol., 2000, 278, (4, Pt. 1), E656-E662). PKC β-1 overexpression augments an increase in endothelial permeability, suggesting an important function in the regulation of the endothelial barrier (Nagpala, P. G., et al., J. Cell Physiol., 1996, 2, 249-55). PKC β mediates activation of neutrophil NADPH oxidase by PMA and by stimulation of Fcy receptors in neutrophils (Dekker, L. V., et al., Biochem. J., 2000, 347, 285-289). Thus, PKC inhibitors may be indicated for use in treating inflammation and asthma.

[0108] Immunological Disorders

[0109] PKC may be useful in treating or ameliorating certain immunological disorders. While one study suggests that HCMV (Human Cytomegalovirus) inhibition is not correlated with PKC inhibition (Slater, M. J., et al., Biorg. & Med. Chem., 1999, 7, 1067-1074), another study showed that the PKC signal transduction pathway synergistically interacted with the cAMP-dependent PKA pathway to activate or increase HIV-1 transcription and viral replication and was abrogated with a PKC inhibitor (Rabbi, M. F., et al., Virology, 1998 (June 5), 245, 2, 257-69). Therefore, an immunological disorder may be treated or ameliorated as a function of the affected underlying pathway's response to up- or down-regulation of PKC.

[0110] PKC β deficiency also results in an immunodeficiency characterized by impaired humoral immune responses and a reduced B cell response, similar to X-linked immunodeficiency in mice, playing an important role in antigen receptor-mediated signal transduction (Leitges, M., et al., Science (Wash., D.C.), 1996, 273, 5276, 788-789). Accordingly, transplant tissue rejection may be ameliorated or prevented by suppressing the immune response using a PKC β inhibitor.

[0111] Dermatological Disorders

[0112] Abnormal activity of PKC has been linked to dermatological disorders characterized by abnormal proliferation of keratinocytes, such as psoriasis (Horn, F., et al., J. Invest. Dermatol., 1987, 88, 220-222; Raynaud, F. and Evain-Brion, D., Br. J. Dermatol., 1991, 124, 542-546). PKC inhibitors have been shown to inhibit keratinocyte proliferation in a dose-dependent manner (Hegemann, L., et al., Arch. Dermatol. Res., 1991, 283, 456-460; Bollag, W. B., et al., J. Invest. Dermatol., 1993, 100, 240-246).

[0113] Oncological Disorders

[0114] PKC activity has been associated with cell growth, tumor promotion and cancer (Rotenberg, S. A. and Weinstein, I. B., Biochem. Mol. Aspects Sel. Cancer, 1991, 1, 25-73; Ahmad, et al., Molecular Pharmacology, 1993, 43, 858-862); PKC inhibitors are known to be effective in preventing tumor growth in animals (Meyer, T., et al., Int. J. Cancer, 1989, 43, 851-856; Akinagaka, S., et al., Cancer Res., 1991, 51, 4888-4892). PKC β-1 and β-2 expression in differentiated HD3 colon carcinoma cells blocked their differentiation, enabling them to proliferate in response to basic FGF (Fibroblast Growth Factor) like undifferentiated cells, increasing their growth rate and activating several MBP (Myelin-Basic Protein) kinases, including p57 MAP (Mitogen-Activated Protein) kinase (Sauma, S., et al., Cell Growth Differ., 1996, 7, 5, 587-94). PKC α inhibitors, having an additive therapeutic effect in combination with other anti-cancer agents, inhibited the growth of lymphocytic leukemia cells (Konig, A., et al., Blood, 1997, 90, 10, Suppl. 1 Pt. 2). PKC inhibitors enhanced MMC (Mitomycin-C) induced apoptosis in a time-dependent fashion in a gastric cancer cell-line, potentially indicating use as agents for chemotherapy-induced apoptosis (Danso, D., et al., Proc. Am. Assoc. Cancer Res., 1997, 38, 88 Meet., 92). Therefore, PKC inhibitors may be indicated for use in ameliorating cell and tumor growth, in treating or ameliorating cancers (such as leukemia or colon cancer) and as adjuncts to chemotherapy.

[0115] PKC α (by enhancing cell migration) may mediate some proangiogenic effects of PKC activation while PKC δ may direct antiangiogenic effects of overall PKC activation (by inhibiting cell growth and proliferation) in capillary endothelial cells, thus regulating endothelial proliferation and angiogenesis (Harrington, E. O., et al., J. Biol. Chem., 1997, 272,11,7390-7397). PKC inhibitors inhibit cell growth and induce apoptosis in human glioblastoma cell lines, inhibit the growth of human astrocytoma xenografts and act as radiation sensitizers in glioblastoma cell lines (Begemann, M., et al., Anticancer Res. (Greece), 1998 (July-August), 18, 4A, 2275-82). PKC inhibitors, in combination with other anti-cancer agents, are radiation and chemosensitizers useful in cancer therapy (Teicher, B. A., et al., Proc. Am. Assoc. Cancer Res., 1998, 39, 89 Meet., 384). PKC β inhibitors (by blocking the MAP kinase signal transduction pathways for VEGF (Vascular Endothelial Growth Factor) and bFGF (basic Fibrinogen Growth Factor) in endothelial cells), in a combination regimen with other anti-cancer agents, have an anti-angiogenic and antitumor effect in a human T98G glioblastoma multiforme xenograft model (Teicher, B. A., et al., Clinical Cancer Research, 2001 (March), 7, 634-640). Accordingly, PKC inhibitors may be indicated for use in ameliorating angiogenesis and in treating or ameliorating cancers (such as breast, brain, kidney, bladder, ovarian or colon cancers) and as adjuncts to chemotherapy and radiation therapy.

[0116] Central Nervous System Disorders

[0117] PKC activity plays a central role in the functioning of the central nervous system (CNS) (Huang, K. P., Trends Neurosci., 1989, 12, 425-432) and PKC is implicated in Alzheimer's disease (Shimohama, S., et al., Neurology, 1993, 43, 1407-1413) and inhibitors have been shown to prevent the damage seen in focal and central ischemic brain injury and brain edema (Hara, H., et al., J. Cereb. Blood Flow Metab., 1990, 10, 646-653; Shibata, S., et al., Brain Res., 1992, 594, 290-294). Accordingly, PKC inhibitors may be indicated for use in treating Alzheimer's disease and in treating neurotraumatic and ischemia-related diseases.

[0118] The long-term increase in PKC γ (as a component of the phosphoinositide 2^(nd) messenger system) and muscarinic acetylcholine receptor expression in an amygdala-kindled rat model has been associated with epilepsy, serving as a basis for the rat's permanent state of hyperexcitability (Beldhuis, H. J. A., et al., Neuroscience, 1993, 55, 4, 965-73). Therefore, PKC inhibitors may be indicated for use in treating epilepsy.

[0119] The subcellular changes in content of the PKC γ and PKC β-II isoenzymes for animals in an in-vivo thermal hyperalgesia model suggests that peripheral nerve injury contributes to the development of persistent pain (Miletic, V., et al., Neurosci. Lett., 2000, 288, 3, 199-202). Mice lacking PKC γ display normal responses to acute pain stimuli, but almost completely fail to develop a neuropathic pain syndrome after partial sciatic nerve section (Chen, C., et al., Science (Wash., D.C.), 1997, 278, 5336, 279-283). PKC modulation may thus be indicated for use in treating chronic pain and neuropathic pain.

[0120] PKC has demonstrated a role in the pathology of conditions such as, but not limited to, cardiovascular diseases, diabetes, diabetes-associated disorders, inflammatory diseases, immunological disorders, dermatological disorders, oncological disorders and central nervous system disorders.

[0121] Glycogen Synthase Kinase-3

[0122] Glycogen synthase kinase-3 (GSK-3) is a serine/threonine protein kinase composed of two isoforms (α and β) which are encoded by distinct genes. GSK-3 is one of several protein kinases which phosphorylate glycogen synthase (GS) (Embi, et al., Eur. J. Biochem, 1980, 107, 519-527). The a and P isoforms have a monomeric structure of 49 and 47 kD respectively and are both found in mammalian cells. Both isoforms phosphorylate muscle glycogen synthase (Cross, et al., Biochemical Journal, 1994, 303, 21-26) and these two isoforms show good homology between species (human and rabbit GSK-3α are 96% identical).

[0123] Diabetes

[0124] Type II diabetes (or Non-Insulin Dependent Diabetes Mellitus, NIDDM) is a multifactorial disease. Hyperglycemia is due to insulin resistance in the liver, muscle and other tissues coupled with inadequate or defective secretion of insulin from pancreatic islets. Skeletal muscle is the major site for insulin-stimulated glucose uptake and in this tissue glucose removed from the circulation is either metabolised through glycolysis and the TCA (tricarboxylic acid) cycle or stored as glycogen. Muscle glycogen deposition plays the more important role in glucose homeostasis and Type II diabetic subjects have defective muscle glycogen storage. The stimulation of glycogen synthesis by insulin in skeletal muscle results from the dephosphorylation and activation of glycogen synthase (Villar-Palasi C. and Larner J., Biochim. Biophys. Acta, 1960, 39, 171-173, Parker P. J., et al., Eur. J. Biochem., 1983, 130, 227-234, and Cohen P., Biochem. Soc. Trans., 1993, 21, 555-567). The phosphorylation and dephosphorylation of GS are mediated by specific kinases and phosphatases. GSK-3 is responsible for phosphorylation and deactivation of GS, while glycogen bound protein phosphatase 1 (PPIG) dephosphorylates and activates GS. Insulin both inactivates GSK-3 and activates PP1G (Srivastava A. K. and Pandey S. K., Mol. and Cellular Biochem., 1998, 182, 135-141).

[0125] Studies suggest that an increase in GSK-3 activity might be important in Type II diabetic muscle (Chen, et al., Diabetes, 1994, 43,1234-1241). Overexpression of GSK-3β and constitutively active GSK-3β (S9A, S9e) mutants in HEK-293 cells resulted in suppression of glycogen synthase activity (Eldar-Finkelman, et al., PNAS, 1996, 93, 10228-10233) and overexpression of GSK-3β in CHO cells, expressing both insulin receptor and insulin receptor substrate 1 (IRS-1) resulted in impairment of insulin action (Eldar-Finkelman and Krebs, PNAS, 1997, 94, 9660-9664). Recent evidence for the involvement of elevated GSK-3 activity and the development of insulin resistance and Type II diabetes in adipose tissue has emerged from studies undertaken in diabetes and obesity prone C57BL/6J mice (Eldar-Finkelman, et al., Diabetes, 1999, 48, 1662-1666).

[0126] Dermatological Disorders

[0127] The finding that transient β-catenin stabilization may play a role in hair development (Gat, et al., Cell, 1998, 95, 605-614) suggests that GSK-3 inhibitors could also be used in the treatment of baldness.

[0128] Inflammatory Diseases

[0129] Studies on fibroblasts from the GSK-3β knockout mouse indicate that inhibition of GSK-3 may be useful in treating inflammatory disorders or diseases through the negative regulation of NFkB activity (Hoeflich K. P., et al., Nature, 2000, 406, 86-90).

[0130] Central Nervous System Disorders

[0131] In addition to modulation of glycogen synthase activity, GSK-3 also plays an important role in the CNS disorders. GSK-3 inhibitors may be of value as neuroprotectants in the treatment of acute stroke and other neurotraumatic injuries (Pap and Cooper, J. Biol. Chem., 1998, 273, 19929-19932). Lithium, a low mM inhibitor of GSK-3, has been shown to protect cerebellar granule neurons from death (D'Mello, et al., Exp. Cell Res., 1994, 211, 332-338) and chronic lithium treatment has demonstrable efficacy in the middle cerebral artery occlusion model of stroke in rodents (Nonaka and Chuang, Neuroreport, 1998, 9(9), 2081-2084).

[0132] Tau and β-catenin, two known in vivo substrates of GSK-3, are of direct relevance in consideration of further aspects of the value of GSK-3 inhibitors in relation to treatment of chronic neurodegenerative conditions. Tau hyperphosphorylation is an early event in neurodegenerative conditions such as Alzheimer's disease and is postulated to promote microtubule disassembly. Lithium has been reported to reduce the phosphorylation of tau, enhance the binding of tau to microtubules and promote microtubule assembly through direct and reversible inhibition of GSK-3 (Hong M. et al J. Biol. Chem., 1997, 272(40), 25326-32). β-catenin is phosphorylated by GSK-3 as part of a tripartite axin protein complex resulting in β-catenin degradation (Ikeda, et al., EMBO J., 1998, 17,1371-1384). Inhibition of GSK-3 activity is involved in the stabilization of catenin hence promotes β-catenin-LEF-1/TCF transcriptional activity (Eastman, Grosschedl, Curr. Opin. Cell Biol., 1999, 11, 233). Studies have also suggested that GSK-3 inhibitors may also be of value in treatment of schizophrenia (Cotter D., et al. Neuroreport, 1998, 9,1379-1383; Lijam N., et al., Cell, 1997, 90, 895-905) and manic depression (Manji, et al., J. Clin. Psychiatry, 1999, 60, (Suppl 2) 27-39 for review).

[0133] Accordingly, compounds found useful as GSK-3 inhibitors could have further therapeutic utility in the treatment of diabetes, dermatological disorders, inflammatory diseases and central nervous system disorders.

[0134] Aspects of the present invention include a method for treating or ameliorating a kinase or dual-kinase mediated disorder in a subject in need thereof comprising administering to the subject a therapeutically effective amount of an instant compound or pharmaceutical composition thereof. The therapeutically effective amount of the compounds of Formula (I) exemplified in such a method is from about 0.001 mg/kg/day to about 300 mg/kg/day.

[0135] Aspects of the present invention include the use of a compound of Formula (I) for the preparation of a medicament for treating or ameliorating a kinase or dual-kinase mediated disorder in a subject in need thereof.

[0136] In accordance with the methods of the present invention, an individual compound of the present invention or a pharmaceutical composition thereof can be administered separately at different times during the course of therapy or concurrently in divided or single combination forms. The instant invention is therefore to be understood as embracing all such regimes of simultaneous or alternating treatment and the term “administering” is to be interpreted accordingly.

[0137] Aspects of the method of the present invention include a compound or pharmaceutical composition thereof advantageously co-administered in combination with other agents for treating or ameliorating a kinase or dual-kinase mediated disorder. For example, in the treatment of diabetes, especially Type II diabetes, a compound of Formula (I) or pharmaceutical composition thereof may be used in combination with other agents, especially insulin or antidiabetic agents including, but not limited to, insulin secretagogues (such as sulphonylureas), insulin sensitizers including, but not limited to, glitazone insulin sensitizers (such as thiazolidinediones) or biguanides or a glucosidase inhibitors.

[0138] The combination product comprises co-administration of a compound of Formula (I) or pharmaceutical composition thereof and an additional agent for treating or ameliorating a kinase or dual-kinase mediated disorder, the sequential administration of a compound of Formula (I) or pharmaceutical composition thereof and an additional agent for treating or ameliorating a kinase or dual-kinase mediated disorder, administration of a pharmaceutical composition containing a compound of Formula (I) or pharmaceutical composition thereof and an additional agent for treating or ameliorating a kinase or dual-kinase mediated disorder or the essentially simultaneous administration of a separate pharmaceutical composition containing a compound of Formula (I) or pharmaceutical composition thereof and a separate pharmaceutical composition containing an additional agent for treating or ameliorating a kinase or dual-kinase mediated disorder.

[0139] The term “subject” as used herein, refers to an animal, preferably a mammal, most preferably a human, who has been the object of treatment, observation or experiment.

[0140] The term “therapeutically effective amount” as used herein, means that amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue system, animal or human, that is being sought by a researcher, veterinarian, medical doctor, or other clinician, which includes alleviation of the symptoms of the disease or disorder being treated.

[0141] The ubiquitous nature of the PKC and GSK isoforms and their important roles in physiology provide incentive to produce highly selective PKC and GSK inhibitors. Given the evidence demonstrating linkage of certain isoforms to disease states, it is reasonable to assume that inhibitory compounds that are selective to one or two PKC isoforms or to a GSK isoform relative to the other PKC and GSK isoforms and other protein kinases are superior therapeutic agents. Such compounds should demonstrate greater efficacy and lower toxicity by virtue of their specificity. Accordingly, it will be appreciated by one skilled in the art that a compound of Formula (I) is therapeutically effective for certain kinase or dual-kinase mediated disorders based on the modulation of the disorder by selective kinase or dual-kinase inhibition. The usefulness of a compound of Formula (I) as a selective kinase or dual-kinase inhibitor can be determined according to the methods disclosed herein and the scope of such use includes use in one or more kinase or dual-kinase mediated disorders.

[0142] Therefore, the term “kinase or dual-kinase mediated disorders” as used herein, includes, and is not limited to, cardiovascular diseases, diabetes, diabetes-associated disorders, inflammatory diseases, immunological disorders, dermatological disorders, oncological disorders and CNS disorders.

[0143] Cardiovascular diseases include, and are not limited to, acute stroke, heart failure, cardiovascular ischemia, thrombosis, atherosclerosis, hypertension, restenosis, retinopathy of prematurity or age-related macular degeneration. Diabetes includes insulin dependent diabetes or Type II non-insulin dependent diabetes mellitus. Diabetes-associated disorders include, and are not limited to, impaired glucose tolerance, diabetic retinopathy, proliferative retinopathy, retinal vein occlusion, macular edema, cardiomyopathy, nephropathy or neuropathy. Inflammatory diseases include, and are not limited to, vascular permeability, inflammation, asthma, rheumatoid arthritis or osteoarthritis. Immunological disorders include, and are not limited to, transplant tissue rejection, HIV-1 or immunological disorders treated or ameliorated by PKC modulation. Dermatological disorders include, and are not limited to, psoriasis, hair loss or baldness. Oncological disorders include, and are not limited to, cancer or tumor growth (such as breast, brain, kidney, bladder, ovarian or colon cancer or leukemia), proliferative angiopathy and angiogenesis; and, includes use for compounds of Formula (I) as an adjunct to chemotherapy and radiation therapy. CNS disorders include, and are not limited to, chronic pain, neuropathic pain, epilepsy, chronic neurodegenerative conditions (such as dementia or Alzheimer's disease), mood disorders (such as schizophrenia), manic depression or neurotraumatic, cognitive decline and ischemia-related diseases {as a result of head trauma (from acute ischemic stroke, injury or surgery) or transient ischemic stroke (from coronary bypass surgery or other transient ischemic conditions)}.

[0144] A compound may be administered to a subject in need of treatment by any conventional route of administration including, but not limited to oral, nasal, sublingual, ocular, transdermal, rectal, vaginal and parenteral (i.e. subcutaneous, intramuscular, intradermal, intravenous etc.).

[0145] To prepare the pharmaceutical compositions of this invention, one or more compounds of Formula (I) or salt thereof as the active ingredient, is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration (e.g. oral or parenteral). Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers may be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.

[0146] Methods of formulating pharmaceutical compositions have been described in numerous publications such as Pharmaceutical Dosage Forms: Tablets, Second Edition, Revised and Expanded, Volumes 1-3, edited by Lieberman, et al.; Pharmaceutical Dosage Forms: Parenteral Medications, Volumes 1-2, edited by Avis, et al.; and Pharmaceutical Dosage Forms: Disperse Systems, Volumes 1-2, edited by Lieberman, et al.; published by Marcel Dekker, Inc.

[0147] In preparing a pharmaceutical composition of the present invention in liquid dosage form for oral, topical and parenteral administration, any of the usual pharmaceutical media or excipients may be employed. Thus, for liquid dosage forms, such as suspensions (i.e. colloids, emulsions and dispersions) and solutions, suitable carriers and additives include but are not limited to pharmaceutically acceptable wetting agents, dispersants, flocculation agents, thickeners, pH control agents (i.e. buffers), osmotic agents, coloring agents, flavors, fragrances, preservatives (i.e. to control microbial growth, etc.) and a liquid vehicle may be employed. Not all of the components listed above will be required for each liquid dosage form.

[0148] In solid oral preparations such as, for example, powders, granules, capsules, caplets, gelcaps, pills and tablets (each including immediate release, timed release and sustained release formulations), suitable carriers and additives include but are not limited to diluents, granulating agents, lubricants, binders, glidants, disintegrating agents and the like. Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be sugar coated, gelatin coated, film coated or enteric coated by standard techniques.

[0149] The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful and the like, an amount of the active ingredient necessary to deliver an effective dose as described above. The pharmaceutical compositions herein will contain, per unit dosage unit, e.g., tablet, capsule, powder, injection, suppository, teaspoonful and the like, of from about 0.001 mg to about 300 mg (preferably, from about 0.01 mg to about 100 mg; and, more preferably, from about 0.1 mg to about 30 mg) and may be given at a dosage of from about 0.001 mg/kg/day to about 300 mg/kg/day (preferably, from about 0.01 mg/kg/day to about 100 mg/kg/day; and, more preferably, from about 0.1 mg/kg/day to about 30 mg/kg/day). Preferably, in the method for treating or ameliorating a kinase or dual-kinase mediated disorder described in the present invention and using any of the compounds as defined herein, the dosage form will contain a pharmaceutically acceptable carrier containing between about 0.01 mg and 100 mg; and, more preferably, between about 5 mg and 50 mg of the compound; and, may be constituted into any form suitable for the mode of administration selected. The dosages, however, may be varied depending upon the requirement of the subjects, the severity of the condition being treated and the compound being employed. The use of either daily administration or post-periodic dosing may be employed.

[0150] Preferably these compositions are in unit dosage forms such as tablets, pills, capsules, powders, granules, lozenges, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, autoinjector devices or suppositories for administration by oral, intranasal, sublingual, intraocular, transdermal, parenteral, rectal, vaginal, inhalation or insufflation means. Alternatively, the composition may be presented in a form suitable for once-weekly or once-monthly administration; for example, an insoluble salt of the active compound, such as the decanoate salt, may be adapted to provide a depot preparation for intramuscular injection.

[0151] For preparing solid pharmaceutical compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as diluents, binders, adhesives, disintegrants, lubricants, antiadherents and glidants. Suitable diluents include, but are not limited to, starch (i.e. corn, wheat, or potato starch, which may be hydrolized), lactose (granulated, spray dried or anhydrous), sucrose, sucrose-based diluents (confectioner's sugar; sucrose plus about 7 to 10 weight percent invert sugar; sucrose plus about 3 weight percent modified dextrins; sucrose plus invert sugar, about 4 weight percent invert sugar, about 0.1 to 0.2 weight percent cornstarch and magnesium stearate), dextrose, inositol, mannitol, sorbitol, microcrystalline cellulose (i.e. AVICEL™ microcrystalline cellulose available from FMC Corp.), dicalcium phosphate, calcium sulfate dihydrate, calcium lactate trihydrate and the like. Suitable binders and adhesives include, but are not limited to acacia gum, guar gum, tragacanth gum, sucrose, gelatin, glucose, starch, and cellulosics (i.e. methylcellulose, sodium carboxymethycellulose, ethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, and the like), water soluble or dispersible binders (i.e. alginic acid and salts thereof, magnesium aluminum silicate, hydroxyethylcellulose (i.e. TYLOSE™ available from Hoechst Celanese), polyethylene glycol, polysaccharide acids, bentonites, polyvinylpyrrolidone, polymethacrylates and pregelatinized starch) and the like. Suitable disintegrants include, but are not limited to, starches (corn, potato, etc.), sodium starch glycolates, pregelatinized starches, clays (magnesium aluminum silicate), celluloses (such as crosslinked sodium carboxymethylcellulose and microcrystalline cellulose), alginates, pregelatinized starches (i.e. corn starch, etc.), gums (i.e. agar, guar, locust bean, karaya, pectin and tragacanth gum), cross-linked polyvinylpyrrolidone and the like. Suitable lubricants and antiadherents include, but are not limited to, stearates (magnesium, calcium and sodium), stearic acid, talc waxes, stearowet, boric acid, sodium chloride, DL-leucine, carbowax 4000, carbowax 6000, sodium oleate, sodium benzoate, sodium acetate, sodium lauryl sulfate, magnesium lauryl sulfate and the like. Suitable glidants include, but are not limited to, talc, cornstarch, silica (i.e. CAB-O-SIL™ silica available from Cabot, SYLOID™ silica available from W. R. Grace/Davison and AEROSIL™ silica available from Degussa) and the like. Sweeteners and flavorants may be added to chewable solid dosage forms to improve the palatability of the oral dosage form. Additionally, colorants and coatings may be added or applied to the solid dosage form for ease of identification of the drug or for aesthetic purposes. These carriers are formulated with the pharmaceutical active to provide an accurate, appropriate dose of the pharmaceutical active with a therapeutic release profile.

[0152] Generally these carriers are mixed with the pharmaceutical active to form a solid preformulation composition containing a homogeneous mixture of the pharmaceutical active of the present invention, or a pharmaceutically acceptable salt thereof. Generally the preformulation will be formed by one of three common methods: (a) wet granulation, (b) dry granulation and (c) dry blending. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from about 0.1 mg to about 500 mg of the active ingredient of the present invention. The tablets or pills containing the novel compositions may also be formulated in multilayer tablets or pills to provide a sustained or provide dual-release products. For example, a dual release tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer, which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric materials such as shellac, cellulose acetate (i.e. cellulose acetate phthalate), polyvinyl acetate phthalate, hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, methacrylate and ethylacrylate copolymers, methacrylate and methyl methacrylate copolymers and the like. Sustained release tablets may also be made by film coating or wet granulation using slightly soluble or insoluble substances in solution (which for a wet granulation acts as the binding agents) or low melting solids a molten form (which in a wet granulation may incorporate the active ingredient). These materials include natural and synthetic polymers waxes, hydrogenated oils, fatty acids and alcohols (i.e. beeswax, carnauba wax, cetyl alcohol, cetylstearyl alcohol and the like), esters of fatty acids metallic soaps and other acceptable materials that can be used to granulate, coat, entrap or otherwise limit the solubility of an active ingredient to achieve a prolonged or sustained release product.

[0153] The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, but are not limited to aqueous solutions, suitably flavored syrups, aqueous or oil suspensions and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable suspending agents for aqueous suspensions, include synthetic and natural gums such as, acacia, agar, alginate (i.e. propylene alginate, sodium alginate and the like), guar, karaya, locust bean, pectin, tragacanth and xanthan gum, cellulosics such as sodium carboxymethylcellulose, methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropyl cellulose and hydroxypropyl methylcellulose and combinations thereof, synthetic polymers such as polyvinyl pyrrolidone, carbomer (i.e. carboxypolymethylene) and polyethylene glycol; clays such as bentonite, hectorite, attapulgite or sepiolite; and other pharmaceutically acceptable suspending agents such as lecithin, gelatin or the like. Suitable surfactants include but are not limited to sodium docusate, sodium lauryl sulfate, polysorbate, octoxynol-9, nonoxynol-10, polysorbate 20, polysorbate 40, polysorbate 60, polysorbate 80, polyoxamer 188, polyoxamer 235 and combinations thereof. Suitable deflocculating or dispersing agent include pharmaceutical grade lecithins. Suitable flocculating agent include but are not limited to simple neutral electrolytes (i.e. sodium chloride, potassium, chloride and the like), highly charged insoluble polymers and polyelectrolyte species, water soluble divalent or trivalent ions (i.e. calcium salts, alums or sulfates, citrates and phosphates (which can be used jointly in formulations as pH buffers and flocculating agents). Suitable preservatives include but are not limited to parabens (i.e. methyl, ethyl, n-propyl and n-butyl), sorbic acid, thimerosal, quaternary ammonium salts, benzyl alcohol, benzoic acid, chlorhexidine gluconate, phenylethanol and the like. There are many liquid vehicles that may be used in liquid pharmaceutical dosage forms, however, the liquid vehicle that is used in a particular dosage form must be compatible with the suspending agent(s). For example, nonpolar liquid vehicles such as fatty esters and oils liquid vehicles are best used with suspending agents such as low HLB (Hydrophile-Lipophile Balance) surfactants, stearalkonium hectorite, water insoluble resins, water insoluble film forming polymers and the like. Conversely, polar liquids such as water, alcohols, polyols and glycols are best used with suspending agents such as higher HLB surfactants, clays silicates, gums, water soluble cellulosics, water soluble polymers and the like. For parenteral administration, sterile suspensions and solutions are desired. Liquid forms useful for parenteral administration include sterile solutions, emulsions and suspensions. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.

[0154] Furthermore, compounds of the present invention can be administered in an intranasal dosage form via topical use of suitable intranasal vehicles or via transdermal skin patches, the composition of which are well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the administration of a therapeutic dose will, of course, be continuous rather than intermittent throughout the dosage regimen.

[0155] Compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, multilamellar vesicles and the like. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, phosphatidylcholines and the like.

[0156] Compounds of the present invention may also be delivered by the use of monoclonal antibodies as individual carriers to which the compound molecules are coupled. The compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include, but are not limited to polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamidephenol, polyhydroxy-ethylaspartamidephenol, or polyethyl eneoxidepolylysine substituted with palmitoyl residue. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, to homopolymers and copolymers (which means polymers containing two or more chemically distinguishable repeating units) of lactide (which includes lactic acid d-, l- and meso lactide), glycolide (including glycolic acid), ε-caprolactone, p-dioxanone (1,4-dioxan-2-one), trimethylene carbonate (1,3-dioxan-2-one), alkyl derivatives of trimethylene carbonate, δ-valerolactone, β-butyrolactone, γ-butyrolactone, ε-decalactone, hydroxybutyrate, hydroxyvalerate, 1,4-dioxepan-2-one (including its dimer 1,5,8,12-tetraoxacyclotetradecane-7,14-dione), 1,5-dioxepan-2-one, 6,6-dimethyl-1,4-dioxan-2-one, polyorthoesters, polyacetalIs, polydihydropyrans, polycyanoacrylates and cross-linked or amphipathic block copolymers of hydrogels and blends thereof.

[0157] Compounds of this invention may be administered in any of the foregoing compositions and dosage regimens or by means of those compositions and dosage regimens established in the art whenever treating or ameliorating a kinase or dual-kinase mediated disorder is required for a subject in need thereof; in particular, whenever treating or ameliorating a kinase disorder mediated by selective inhibition of a kinase selected from protein kinase C or glycogen synthase kinase-3 is required; and, whenever treating or ameliorating a kinase disorder mediated by dual inhibition of at least two kinases selected from protein kinase C and glycogen synthase kinase-3 is required; and, more particularly, whenever treating or ameliorating a kinase disorder mediated by selective inhibition of a kinase selected from protein kinase C α, protein kinase C β-II, protein kinase C γ or glycogen synthase kinase-3β is required; and, whenever treating or ameliorating a kinase disorder mediated by dual inhibition of at least two kinases selected from protein kinase C α, protein kinase C β-II, protein kinase C γ or glycogen synthase kinase-3β is required.

[0158] The daily dose of a pharmaceutical composition of the present invention may be varied over a wide range from about 0.7 mg to about 21,000 mg per 70 kilogram (kg) adult human per day; preferably in the range of from about 7 mg to about 7,000 mg per adult human per day; and, more preferably, in the range of from about 7 mg to about 2,100 mg per adult human per day. For oral administration, the compositions are preferably provided in the form of tablets containing, 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250 and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the subject to be treated. A therapeutically effective amount of the drug is ordinarily supplied at a dosage level of from about 0.001 mg/kg to about 300 mg/kg of body weight per day. Preferably, the range is from about 0.1 mg/kg to about 100 mg/kg of body weight per day; and, most preferably, from about 0.1 mg/kg to about 30 mg/kg of body weight per day. Advantageously, compounds of the present invention may be administered in a single daily dose or the total daily dosage may be administered in divided doses of two, three or four times daily.

[0159] Optimal dosages to be administered may be readily determined by those skilled in the art and will vary with the particular compound used, the mode of administration, the strength of the preparation and the advancement of the disease condition. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to an appropriate therapeutic level.

The mixture was stirred under an argon atmosphere at rt for 1 h, then the temperature was raised to 50° C. for 4 h. The mixture was stirred at rt overnight. The resulting white solids were removed by filtration, then partitioned between 600 mL of ether and 300 mL of water. The organic layer was washed with water (3×) and brine, then dried over anhydrous sodium sulfate. The solvent was removed in vacuo and the resulting oily residue triturated with hexane to give a crude solid product.

[0226] Glycogen Synthase Kinase-3 Assay

[0227] Compounds were tested for the ability to inhibit recombinant rabbit GSK-3β using the following protocol. The test compound was added to a reaction mixture containing Protein phosphatase inhibitor-2 (PPI-2) (Calbiochem) (45 ng), rabbit GSK-3β (New England Biolabs) (0.75 units) and ³³P-ATP (1 μCi) in 50 mM Tris-HCl (pH 8.0), 10 mM MgCl₂, 0.1% BSA, 1 mM DTT and 100 μM Sodium Vanadate. The mixture was reacted for 90 minutes at 30° C. to allow phosphorylation of the PPI-2 protein and then the protein in the reaction was precipitated using 10% TCA. The precipitated protein was collected on filter plates (MultiScreen-DV/Millipore), which were subsequently washed. Finally, the radioactivity was quantified using a TopCount Scintillation Counter (Packard). GSK-3 inhibitory compounds resulted in less phosphorylated PPI-2 and thus a lower radioactive signal in the precipitated protein. Staurosporine or Valproate, known inhibitors of GSK-3β, were used as a positive control for screening.
